Description

Technical Field

[0001] This utility model relates to the field of pipe fitting production mold technology, specifically to an internal shrinkage mold structure for pipe fitting production. Background Technology

[0002] In the production process of pipe fittings, molds are an essential forming equipment.

[0003] In the existing technology, because the inner wall of the pipe fitting has a coil structure, the mold will form an inner undercut structure inside it. As a result, when the mold is demolded, the protruding structure on it gets stuck in the coil groove, thus preventing normal demolding. Therefore, it is necessary to improve the internal shrinkage mold structure for pipe fitting production to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an internal shrinkage mold structure for pipe fitting production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an internal shrinkage mold structure for pipe fitting production, including a base plate, a push plate movably mounted on the top of the base plate, a feeding plate disposed inside the top of the push plate, an internal shrinkage mechanism disposed inside the base plate extending into the push plate, and a pipe fitting component disposed outside the internal shrinkage mechanism.

[0006] The retraction mechanism includes a base, which is fixedly installed inside the base plate. A connecting column is fixedly installed on the top of the base, and a retraction rod is fixedly installed on the top of the connecting column. A limiting seat is fixedly installed inside the bottom end of the push plate, and a first retraction component and a second retraction component are movably installed inside the feeding plate.

[0007] Preferably, the base is fixedly installed inside the base plate by bolts.

[0008] Preferably, the bottom of the connecting column is provided with a threaded hole, and the connecting column is fixedly installed to the inner rod by bolts.

[0009] Preferably, the top of the push plate has a groove, and the feeding plate is embedded in the groove.

[0010] Preferably, the bottom of the push plate is provided with a first mounting groove, the bottom of the feeding plate is provided with a second mounting groove, and the limiting seat is fixedly installed inside the first mounting groove and the second mounting groove, and the inner retraction rod is slidably installed inside the limiting seat.

[0011] Preferably, there are three of each of the first and second retractable members, arranged in a circular array, and the second retractable member is slidably installed between two adjacent first retractable members.

[0012] Preferably, the outer wall of the retractable rod is provided with six limiting grooves and six protrusions. The inner sides of the first retractable member and the second retractable member are provided with protrusions, and the protrusions are slidably installed inside the limiting grooves. The six protrusions are slidably installed between the first retractable member and the second retractable member. The first retractable member and the second retractable member are installed at an angle, and the size of the retractable rod gradually decreases from bottom to top.

[0013] Compared with the prior art, this utility model provides an internal shrinkage mold structure for pipe fitting production, which has the following beneficial effects:

[0014] The internal shrinkage mold structure for producing this pipe fitting separates from the base plate by moving the push plate upward, thereby allowing the internal shrinkage rod to slide between the first and second internal shrinkage parts. At this time, the first and second internal shrinkage parts shrink inward without the support of the internal shrinkage rod, thus allowing the first and second internal shrinkage parts to slide inward. Due to the reduction in size, it is easier to demold the pipe fitting. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Please see Figure 1-8 This utility model provides a technical solution: an internal shrinkage mold structure for pipe fitting production, including a base plate 1, a push plate 2 movably installed on the top of the base plate 1, a feeding plate 3 provided inside the top of the push plate 2, an internal shrinkage mechanism 4 provided inside the base plate 1 extending to the inside of the push plate 2, and a pipe fitting component 5 provided outside the internal shrinkage mechanism 4.

[0028] The internal shrinking mechanism 4 includes a base 41, which is fixedly installed inside the base plate 1. A connecting column 42 is fixedly installed on the top of the base 41, and an internal shrinking rod 43 is fixedly installed on the top of the connecting column 42. A limiting seat 46 is fixedly installed inside the bottom end of the push plate 2. A first internal shrinking component 44 and a second internal shrinking component 45 are movably installed inside the discharge plate 3 to facilitate internal shrinking demolding of the first internal shrinking component 44 and the second internal shrinking component 45.

[0029] Furthermore, the base 41 is fixedly installed inside the base plate 1 by bolts, which facilitates the installation of the base 41.

[0030] Furthermore, the bottom of the connecting column 42 is provided with a threaded hole, and the connecting column 42 is fixedly installed with the inner retraction rod 43 by bolts, which facilitates the fixed installation of the connecting column 42 and the inner retraction rod 43.

[0031] Furthermore, the top of the push plate 2 is provided with a groove, and the feeding plate 3 is embedded in the groove, which makes it easy to install the feeding plate 3 inside the push plate 2.

[0032] Furthermore, the bottom of the push plate 2 is provided with a first mounting groove, the bottom of the discharge plate 3 is provided with a second mounting groove, and the limiting seat 46 is fixedly installed inside the first mounting groove and the second mounting groove. The inner retraction rod 43 passes through the limiting seat 46 and is slidably installed inside it, so as to facilitate the fixed installation of the limiting seat 46.

[0033] Furthermore, there are three of each of the first inner shrinking member 44 and the second inner shrinking member 45, which are arranged in a circular array. The second inner shrinking member 45 is slidably installed between two adjacent first inner shrinking members 44, so that the first inner shrinking member 44 and the second inner shrinking member 45 can slide together.

[0034] Furthermore, the outer wall of the retractable rod 43 is provided with six limiting grooves and six protrusions. The inner sides of the first retractable member 44 and the second retractable member 45 are provided with protrusions, and the protrusions are slidably installed inside the limiting grooves. The six protrusions are slidably installed between the first retractable member 44 and the second retractable member 45. The first retractable member 44 and the second retractable member 45 are installed at an angle, and the size of the retractable rod 43 gradually decreases from bottom to top, which facilitates the control of the sliding of the first retractable member 44 and the second retractable member 45 through the retractable rod 43.

[0035] In actual operation, when this device is used, the base plate 1 is fixed, and the push plate 2 is connected to the drive structure. The drive structure drives the push plate 2 to move upward, causing the push plate 2 to separate the material feeding plate 3 from the base plate 1. At this time, the inner shrink rod 43 is fixedly installed on the base plate 1 by the connecting column 42 and the base 41. When the push plate 2 moves upward, the inner shrink rod 43 moves downward relative to the push plate 2. As the inner shrink rod 43 moves downward, it separates from the first inner shrink part 44 and the second inner shrink part 45. The first inner shrink part 44 and the second inner shrink part 45 lose the support of the inner shrink rod 43. At this time, the first inner shrink part 44 and the second inner shrink part 45 slide and retract inward, thereby realizing demolding from the tube part 5.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
